<p>if you fill out the estimator on the princeton financial aid site, you should get a good picture as to whether or not you can apply ed. Assuming that all of the information that you put into the estimator is correct, theyre generally extremely close to the number given by the estimator, if that number works for you, then she could apply ed, if it doesnt then she could apply rd, but realize that that is the number that she will probably end up with, and thus should possibly focus more on a school that offers merit aid as well</p>
